Micro-pipet

A micro-pipet is a tool used in a laboratory to transfer a measured volume of liquid. A micro-pipet is often used when filling wells in an electrophoresis gel.

Punnet square to predict F1

Punnet squares predict what alleles an offspring will have when mating plants and animals. This graphic predicts what alleles will be passed on in the first generation between a normal parent and a lesion parent.

Punnet square to predict F2 Generation

Punnet squares predict what alleles an offspring will have when mating plants and animals. This graphic predicts what alleles will be passed on in the second, or F2, generation between two F1 parents.

Gene Gun Ammunition

When using a gene gun, the gene gun ammunition is a “bullet” made from particles which have been coated in DNA. The bullet is then fired into a petri dish with a sampling of cells, and the particles introduce the DNA to the cells.

Loading a gel

In gel electrophoresis, DNA samples are loaded into slots in agarose gel, known as wells, using a micro-pipet. The DNA samples are colorless, but a blue tracking dye can be added to the sample so that the DNA can be visually tracked as it moves through the gel.

Centrifuge

In the centrifuge, an object is put in rotation around a fixed axis, applying a force perpendicular to the axis. The centrifuge is used to separate material from the mediums they are mixed with. In a DNA lab, a centrifuge can be used in DNA extraction.

Nucleus

The nucleus is a membrane bound structure that contains DNA and RNA – the cell’s hereditary information. It controls the cell’s growth and reproduction.

Anther

The anther is the portion of the male reproductive part of the plant where the pollen is produced.

Hand Planter

In seed research, breeders are often working with a small number of seeds as they work with plant crosses. This hand planter allows someone to plant seeds one at a time – instead of using a mechanical planter.

Stigma

The stigma is a portion of the flower’s male reproductive part. The stigma receives pollen during pollination. In addition, pollen germinates in the stigma.

Stamen

The stamen is the portion of the male reproductive portion of the plant where the pollen is produced. The stamen consists of the filament and the anther.

Style

The style is the main reproductive organ of the plant. The style is made up of the ovary, the stigma and the style. The style connects the stigma with the ovary and facilitates the growth of the pollen tubes.

Cell wall

The cell wall is the layer that surrounds some types of cells. The cell wall is located outside the cell membrane and provides these cells with structural support and protection, in addition to acting as a filtering mechanism.

Chromosomes

Chromosomes are thread-like structures found in the nucleus of the cell. Each chromosome contains DNA, protein, and RNA.

Sepal

The sepal of the plant protects the flower bud and provides support for the petals when in bloom.

Central Vacuole

The central vacuole is a storage compartment found within the cell. Vacuoles can store food or nutrients that a cell might need to survive. They can also store waste products so the rest of the cell is protected from contamination.

Micro-centrifuge tubes

Micro-centrifuge small tubes are used to store and centrifuge small amounts of liquid.

Ovary

In flowering plants, the ovary is the female reproductive organ – the enlarged portion of the pistil. The ovary holds the ovule.

Shoot bag

In controlled cross pollinating, shoot bag is used to cover the silks on the young corn ear shoots. The bag keeps pollen from moving from nearby plants onto the silks.

Agarose gel

Agarose gel, also called Agar gel, is used as a medium for growing cultures and used to conduct gel electrophoresis tests.

Protein Test Strips

Protein test strips are used to detect the presence of proteins in a substance. It is most frequently used to detect the presence of GMOs.

Incubator

An incubator is used to grow and maintain microbiological cultures or cell cultures.

Who works with this?

The plant transformation specialist uses this to grow colonies of Agrobacterium.  She then uses the Agrobacterium to deliver the transgene to plant cells.

Ovule

The ovule contains the female reproductive cells (“egg”) and develops into a seed when fertilized.

Who works with this?

The breeder wants these to develop into seeds as a result of making a cross.

It’s the job of the transgene designer to identify these gene regions and put them together.
